Some time ago I installed a small business server2003 with ISA 2000 for a client. I configured the USB ADSL modem to connect to the net and set up packet filtering according to Microsofts recomendations. The small business server only had one network card serving the internal network. All the clients on the network, as well as the small business server ran F-secure client security (which also has it's own client firewall). I hadn't experienced any problems with the installation except spam from thier external emails and one virus infestation which wa quickly retified. Although a router would have been preferable for the installation, my question is was the installation I've outlined above wrong?
my thoughts on the ISA server was that it handled the web access and therefore the server was protected behind the firewall.... in this case the sbs and the ISA were on the same server.
Thanks in advance
